Be Seen! When out on your kayak, you are very low to the water. Add to that any wave or swell action and you are often hidden from other boaters view. The 4' tall safety flag will help other boaters see you. Very important in areas with mixed boating traffic! For mounting in areas with internal access, you can use large washers and the provided nuts for mounting. Otherwise, in areas with no internal access, use the mount which includes bolts and well nuts.
